Last Saturday Tommy Caldwell racked up for what could be the hardest big-wall free climb in the world, El Capitan’s Dawn Wall.

Now he has cranked through pitches one through nine and is currently projecting the 5.14a/b 10th pitch.  

“Feels crazy up here with this 40 mph up draft tonight,” posted Caldwell on Facebook yesterday from El Cap.  “I hope it blows me right up this pitch. 7 tries so far on pitch 10!!! Grrrrrr.”

Caldwell has already surmounted several difficulties between pitches one and 10, including a 5.14a on pitch 7 directly followed by a 5.13d and 5.13c for pitches eight and nine.

After spending last night attempting pitch 10 by headlamp during a windstorm, Caldwell posted, “No send tonight. But the craziness of the situation struck me. Trying to climb 5.14 by headlamp during a super intense windstorm. Strangely invigorating. I love the experience but am still overwhelmed by the magnitude of this project. “
